Pronunciation

  • Classical: [prae̯ˈjuː.dɪ.koː][1]
  • Ecclesiastical: [preˈjuː.di.ko][1]

Forms

praeiūdicō (present infinitive praeiūdicāre, perfect active praeiūdicāvī, supine praeiūdicātum); first conjugation[1]

Etymology

It is from Latin prae- + iūdicō (“to judge”).[2][3][1] The verb iūdicō is made from iūdex (“judge”), which de Vaan derives from Proto-Italic *jowes-dik- (“judge”), one who speaks the law, a compound of the words behind iūs2 (“law”) and dīcō2 (“to say”).[4]

Earliest recorded meaning

The OLD's first examples are in Cicero,[2] and the TLL counts nine passages in his works.[3] In the speech for Cluentius he speaks of a man who came to trial after the matter had been prejudged once and again: rē semel atque iterum praeiūdicātā.[2][5]

Semantic evolution

It was first a legal term, to give a preliminary judgement on a matter before the main trial.[2][6] Livy uses it more widely of settling something in advance,[2] and it is also used of forming an opinion beforehand.[2][5] The participle praeiūdicātus meant decided beforehand, as in opīniō praeiūdicāta, a preconceived opinion.[5][6]

In later Latin it was also intransitive with a dative, to be prejudicial to: the jurist Macer, in the Digest, says that matters judged between some people do not prejudice others.[2][6] Ambrose uses it in this sense too,[6] and Church Latin kept the meaning “to decide beforehand”.[7]
